However, after high-temperature dust-laden exhaust gas passes through the waste heat boiler, in addition to the temperature reduction, some dust particles will settle, which may cause blockage of equipment. and corrosion, which will affect the service life of the equipment; in order to strengthen environmental protection and avoid energy waste, the furnace gas must be dedusted by a filter device before being discharged or recycled. In this process, a pre-dust device is usually used to remove the dispersed dust The particles are separated from the high temperature exhaust gas.

Among the existing pre-dust removal devices: the gravity sedimentation dedusting device is only suitable for purifying dust with high density and coarse particle size; the inertial dedusting device has a simple structure and low resistance (10-80 mm water column), but the purification efficiency is low (40-80 mm water column). 80%); although the use of bag dust removal is highly efficient, since the maximum instantaneous temperature of the cloth bag is only 280°C, in order to meet the needs of the filter, a huge surface cooler or mechanical air cooler needs to be added at the front end. During the above heat exchange process, while the temperature drops, a large amount of heat energy is also lost, resulting in direct economic losses.

Because the chamber pressure spring 2 squeezes the friction block 2, the friction block 2 and the friction block are blown out. There is still friction between the first, the friction between the second friction block and the first friction block and the resultant force of the gas in the ash box to the chamber pressure control slider is greater than the elastic force of the chamber pressure spring one, and the chamber pressure control slider remains stationary.

In specific use, the air outlet channel 3 53 is connected to the waste heat boiler, and the high-temperature exhaust gas flows into the rear insulation pipe 12 from the air inlet 11, and then passes through the self-rotating solid-gas one-way separation device 2, the vertical wall ash cleaning device 3, the connecting pipe 13 and In the exhaust box 4225, when the high-temperature exhaust gas flows through the self-rotating solid-gas one-way separation device 2 through the thermal insulation assembly 1, the exhaust gas will drive the rotating fan 22 to rotate, and the rotating fan 22 drives the central shaft 23, the upper bracket 26, the lower bracket 27 and the dust removal board 28 does concentric rotation, because the rotating fan 22 is inclined on the central axis 23, when the gas flowing in the vertical direction encounters the rotating fan 22, it will generate a horizontal component force on the rotating fan 22, and push the rotating fan 22 to rotate, Since the action of the force is mutual, the rotating fan 22 will exert a horizontal reaction force on the gas, and the rotating fan 22 will push the dust to fly into the brush one 24 through the horizontal reaction force exerted on the gas, and the dust removal plate 28 and the rotating The fan 22 rotates concentrically and the dust removal plate 28 extends into the brush one 24. The dust removal plate 28 beats the brush one 24, so that the dust on the brush one 24 moves to the brush one 24 under the action of the dust removal plate 28 and the inertial force. At one end, the fluff part of the other end of the brush one 24 blocks the passage of high-speed airflow, one end of the brush one 24 and the pipe wall one 21 form a sinking channel with no resistance to solid dust, and at the brush one 24 The gas in the other end of the fluff has a low density and small volume, and the gas in the tail gas can flow freely and rise through the fluff, while the dust as a solid particle has a high density and a large volume, and when passing through the fluff, the resistance is greater and it is difficult to move. The flowing gas no longer has enough flow rate to drive the dust to continue to move. The dust is shot into one end of the brush 24 by the dust removal plate 28, and continuously descends and accumulates on the ash falling component 43 under the action of gravity. Initially, the vertical wall cleaning device 3. Rest on the limiter 6 at the bottom, and the rotating blade 312 is in an open state. When the exhaust air passes through the vertical wall cleaning device 3, due to the large resistance of the rotating blade 312 to the air flow, the airflow is opposite to the vertical wall cleaning device 3. The force is greater than the downward force received by the vertical wall cleaning device 3, and the vertical wall cleaning device 3 will accelerate upward along the limit rod 7 under the action of the air flow. The position rod 7 rolls clockwise, and drives the first gear 3154 to rotate clockwise, the first gear 3154 drives the second gear 3155 and the crankset 3156 to rotate counterclockwise, the crankset 3156 drives the third gear 3157 to rotate clockwise, and the third gear 3157 rotates clockwise. The gear 3157 drives the fourth gear 3158 to rotate counterclockwise, the fourth gear 3158 drives the sixth gear 31510 and the fifth gear 3159 to rotate clockwise, the fifth gear 3159 drives the external teeth 3143 to rotate clockwise, and the external teeth 3143 drives the rotating disk 313 to rotate around the limit The position rod 7 rotates clockwise, and at the same time, the outer teeth 3143 drive the seventh gear 31511 to revolve clockwise along the inner teeth 3132 at the same time, and the rotating blades 312 are gradually closed by the seventh gear 31511. 31 The upward force gradually becomes smaller and eventually smaller than the upward force. Under the downward force, the upward movement speed of the vertical wall cleaning device 3 changes from upward acceleration to upward deceleration. Before the upward movement speed of the vertical wall cleaning device 3 is reduced to 0m/s, the vertical wall cleaning device 3 and the thermal insulation assembly 1 are above. The limit frame 6 is in contact, and the speed of the vertical wall cleaning device 3 becomes 0 m/s under the blocking of the limit frame 6. At this time, the rotating blade 312 has been completely retracted into the resistance alternator 31, and then the vertical wall cleaning device 3 is under gravity. Under the action of the vertical wall cleaning device 3, the power wheel 3153 rolls counterclockwise along the limit rod 7, and drives the first gear 3154 to rotate counterclockwise, and the first gear 3154 drives the second gear 3155 and the teeth The plate 3156 rotates clockwise, the tooth plate 3156 drives the third gear 3157 to rotate counterclockwise, the third gear 3157 drives the fourth gear 3158 to rotate clockwise, the fourth gear 3158 drives the sixth gear 31510 and the fifth gear 3159 to rotate counterclockwise , the fifth gear 3159 drives the outer teeth 3143 to rotate counterclockwise, the outer teeth 3143 drives the rotating plate 313 to rotate counterclockwise around the limit rod 7, and the outer teeth 3143 drive the seventh gear 31511 to rotate along the inner teeth 3132 while clockwise. Revolving counterclockwise, driven by the seventh gear 31511, the rotating blade 312 gradually opens, the resistance alternator 31 is gradually increased by the upward force, and finally exceeds the downward force, the downward movement speed of the vertical wall cleaning device 3 The change is from downward acceleration to downward deceleration. Before the downward movement speed of the vertical wall cleaning device 3 is reduced to 0 m/s, the vertical wall cleaning device 3 is in contact with the limit frame 6 under the thermal insulation assembly 1. The speed of the vertical wall ash cleaning device 3 becomes 0 m/s under the blocking of 6, and the rotating blade 312 is fully opened at this time, and the continuous up and down movement of the vertical wall ash cleaning device 3 is realized by the power of the exhaust gas; one end of the support rod 32 is set at the resistance intersection. On the inverter 31, the second pipe wall 33 is arranged on the other end of the support rod 32, the second brush 34 is arranged on the second pipe wall 33, and the second brush 34 is in sliding contact with the vertical wall of the thermal insulation assembly 1. When the rod 7 moves up and down, the second brush 34 cleans the dust on the vertical wall of the thermal insulation component 1, uses the principle of excess action to completely clean the dust on the vertical wall of the thermal insulation component 1, and uses the vertical wall dust cleaning device 3 and the limit frame 6. The collision shakes off the dust on the brush 2 34, and the shaken off dust falls through the sinking channel formed by one end of the brush 1 24 and the pipe wall 1 21 and has no resistance to solid dust and the outside of the constriction 16 of the insulation pipe. On the ash assembly 43, with the increase of smoke and dust on the ash falling assembly 43, under the action of the dust gravity, the special-shaped plate 432 overcomes the elastic force of the return spring 433 and the attractive force of the return magnetic piece 431 to rotate counterclockwise around the rotation axis 1 434, which When the heat preservation assembly 1 is communicated with the ash box 42, the dust falls into the ash box 42; after the dust falls into the ash box 42, the airflow in the insulation pipe 12 will rush into the ash box 42, and the special-shaped plate 432 exerts a downward pressure, the special-shaped plate 432 cannot return to its original position, and the ash falling assembly 43 is always in the open state, The exhaust gas enters the ash box 42 through the through hole 425, the air pressure in the ash box 42 gradually increases, the chamber pressure control slider 4216 is subjected to leftward pressure, and the exhaust box air pressure control slider 4223 is subjected to rightward pressure. The first block 4212 and the second friction block 4213 cannot be compressed and can only slide each other. Before the leftward force of the second friction block 4213 is greater than the maximum static friction force between the second friction block 4213 and the first friction block 4212, the chamber pressure control slider 4216 The position of the ash outlet remains the same, and the ash outlet 424 is always in a sealed state. Since the tail box spring 4224 is compressible, the tail box air pressure control slider 4223 moves to the right to squeeze the tail box spring 4224 and seal the air outlet 4226. When the box air pressure control slider 4223 cannot move, the air pressure in the ash box 42 gradually rises until it is equal to the air pressure in the heat preservation assembly 1. Under the action of the return spring 433, the special-shaped plate 432 returns to its original position, and the exhaust gas passes through the heat preservation assembly 1. It flows into the exhaust box 4225. Since the air outlet 1 4226 in the exhaust box 4225 is sealed, only the air outlet 4227 is discharged. The air intake speed of the exhaust box 4225 is higher than the air outlet speed, and the air pressure of the exhaust box 4225 increases, and finally pushes The exhaust box air pressure control slider 4223 moves to the left to further increase the air pressure in the ash box 42, and the leftward pressure on the chamber pressure control slider 4216 further increases and exceeds the friction block 1 4212 and the friction block 2 4213. The maximum static friction force between the friction block two 4213 and the friction block one 4212 overcomes the friction force between the two friction blocks 4212 and slides to the left. , the chamber pressure control slider 4216 moves to the left rapidly under the action of the air pressure in the ash box 42, the chamber pressure spring 1 4214 and the chamber pressure spring 2 4215 are compressed, the ash outlet 424 is opened, and under the action of the air pressure, the furnace ash The dust in the box 42 is blown out, and the air pressure in the ash box 42 is reduced. Since the chamber pressure spring two 4215 squeezes the friction block two 4213, there is still friction between the friction block two 4213 and the friction block one 4212, and the friction block The friction force between the second 4213 and the friction block 1 4212 and the resultant force of the gas in the ash box 42 to the chamber pressure control slider 4216 are greater than the elastic force of the chamber pressure spring 1 4214, the chamber pressure control slider 4216 remains stationary, when the ash box 42 When the air pressure in 42 is the same as the atmospheric pressure, the dust is no longer blown out, and the elastic force of the chamber pressure spring 1 4214 is greater than the friction force between the friction block 2 4213 and the friction block 1 4212. Under the action of the chamber pressure spring 4214, the chamber pressure controls the sliding The block 4216 overcomes the frictional force and moves to the right and contacts the second limit block 4217, sealing the ash outlet 424 again; When the internal air pressure decreases, under the action of the elastic force of the exhaust box spring 4224, the exhaust box air pressure control slider 4223 moves to the right to release the seal on the air outlet 1 4226; After the exhaust gas of the pipe 12 is cleaned of dust, it flows into the exhaust box 4225 through the connecting pipe 13, and finally flows into the waste heat boiler through the gas outlet channel 3 53 for waste heat recovery; when the boiler is overhauled, the chamber pressure can be controlled through the tie rod port 423 and the threaded hole 8. The slider 4216 is pulled to the left, the ash outlet 424 is opened, and the exhaust fan is connected to the ash outlet 424 to extract air, so that the residual dust in the heat preservation pipe 12 and the ash box 42 can be cleaned.
